Activision Releases Call Of Duty: World At War: Zombies II
June 3, 2010

Just like in the original version, other maps, which in this case include Verrückt and Nacht Der Untonen, can be downloaded for $4.99 each as in-app purchases. The game also still features four-player online co-op, achievements, customizable controls, and leaderboards.
Those of you who already own the original won't be forced to pay the full $9.99 asking price to get the new map and other new items. After downloading the update, you will simply be able to upgrade to Call of Duty: World at War: Zombies II via a $4.99 in-app purchase. Sure, it's still a little expensive, but it's the same price as a single map and you get all of the other new items.
Alright, that's enough reading. It's time to get your zombie slaying on.
